FRICTION-CLUTCH.

SPECIFICATION forming part of Letters Patent No. 318,905, dated May 26,1885.

Application filed March 31, 1885.

'full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part ofthis'specification, in

- which similar letters of reference indicate corresponding parts in allthe figures.

Figure 1 is a side elevation of my improved frictionclutch. Fig. 2 is anedge view partly in section. Fig. 3 is a detail view of the triot-ion-ring, and Fig. 4 is aperspective view of the clutch-arm.

The object of my invention is to provide a simple and effectivefriction-clutch for arresting or retarding the movement of machinery, tobe applied to any use requiring a clutch of this description.

My invention consists in a grooved wheel attached to the shaft whosemotion is to be controlled, and in the combination therewith of a splitring received by the groove and provided with wedge-shaped earsprojecting therefrom near opposite sides of the slot of the ring, anapertured arm adapted to receive the wedge-shaped ears, and a leverturning on the shaft and pivoted to the arm, all as here inafter morefully described.

The wheel A, secured to the shaft B, has a peripheral groove, (1, towhich is fitted a slot ted ring, 0, provided with wedge-shaped ears I)at opposite sides of the slot 0. The ring 0 is larger in internaldiameter than the wheel A at the bottom of the groove a, so that whenthe said ring is allowed to spring apart so as (No model.)

to assume its normal shape it will fit loosely on the wheel A. Upon theshaft B is placed a lever, D, to which is pivoted one end of the arm E,the opposite end of the arm being bent at right angles over the edge ofthe wheel A, the bent portion having an aperture to receive thewedge-shaped ears b, projecting from the slotted ring C.

W'hen the arm E is raised, so as to embrace the outer and narrower partsof the ears b, the ring 0 is allowed to expand, and the wheel A mayrevolve freely therein. By moving the lever D so as to bring theapertured end of the arm E into engagement with the inclined sides ofthe wedge-shaped ears I), the ring 0 is contracted more or less and madeto exert more or less pressure upon the periphery of the wheel A.

Having thus described my invention, Iclaim as new and desire to secureby Letters Patent 1. The combination, in a friction-clutch, of afriction-wheel, a slotted ring, provided with wedge-shaped ears atopposite sides of the slot, and an apertured arm adapted to engage thewedge-shaped ears of the slotted ring, substantially as herein shown anddescribed.

2. The combination, in a friction-clutch, of the wheel A, the slottedring 0, provided with wedge-shaped ears I), the apertured arm E,embracing the said wedge-shaped ears, and the lever D, pivoted to thearm E and turning on the shaft B, as herein described.
